WebExcessive nutrients lead to algal blooms and low-oxygen (hypoxic) waters that can kill fish and seagrass and reduce essential fish habitats. Many of these estuaries also support bivalve mollusk populations (e.g., oysters, clams, scallops), which naturally reduce nutrients through their filter-feeding activities. WebScientists refer to hypoxic waters as those waters where oxygen concentrations are below two milligrams per liter. Now, organisms that can swim away from those conditions do, they flee, and so they avoid hypoxic waters. But not always.
